The Erythropoietin With Anemia Table Test evaluates how erythropoietin production aligns with anemia status by comparing hormone levels to hemoglobin. Abnormal patterns may suggest kidney disease, bone marrow dysfunction, or other systemic conditions. This test provides information about red blood cell production, oxygen balance, and overall hematologic health in the presence of anemia.
The Erythropoietin (EPO) Test measures levels of erythropoietin, a hormone made by the kidneys that stimulates red blood cell production. Abnormal levels may indicate anemia, chronic kidney disease, or bone marrow disorders. Elevated EPO can also occur with low oxygen levels or tumors. Doctors order this test for patients with unexplained fatigue, shortness of breath, or abnormal blood counts. Results help guide diagnosis, treatment, and monitoring of anemia-related conditions.
The Intrinsic Factor Blocking Antibody Test detects antibodies that interfere with intrinsic factor, a protein essential for vitamin B12 absorption. The presence of these antibodies is strongly associated with pernicious anemia, an autoimmune cause of B12 deficiency. Doctors use this blood test to help confirm diagnosis, distinguish the cause of anemia, and guide treatment for patients experiencing fatigue, weakness, or neurological symptoms related to low B12.
The Folate RBC Test measures folate levels inside red blood cells, providing a more accurate reflection of long-term folate status than serum tests. Folate is essential for DNA synthesis, red blood cell production, and nervous system health. Low levels may indicate poor diet, malabsorption, or anemia. Doctors order this test for patients with fatigue, weakness, or neurological issues. Results help diagnose folate deficiency and guide nutritional treatment.
The Reticulocyte Count Test measures immature red blood cells (reticulocytes) to evaluate bone marrow function and red cell production. High levels may indicate blood loss, hemolytic anemia, or recovery from treatment, while low levels may suggest bone marrow failure, nutritional deficiencies, or chronic disease. Doctors use this test to assess anemia, monitor therapy, or track recovery. Results provide key insight into red blood cell health and overall hematologic function.
The Parietal Cell Antibody Test detects autoantibodies against stomach parietal cells, which produce intrinsic factor and stomach acid. Their presence is strongly associated with pernicious anemia, vitamin B12 deficiency, and autoimmune gastritis. Doctors use this blood test to help diagnose the cause of anemia, investigate digestive issues, and evaluate patients with suspected autoimmune disorders affecting stomach function and nutrient absorption.
The Hemoglobin Test measures the amount of hemoglobin in blood, the protein that carries oxygen to tissues. Low hemoglobin may indicate anemia, blood loss, or nutritional deficiencies, while high levels may suggest dehydration, lung disease, or bone marrow disorders. Doctors order this test to evaluate fatigue, weakness, or shortness of breath. Results provide key insight into oxygen transport, red blood cell health, and overall hematologic function.
The Direct Antiglobulin Test with Reflex to Anti C3 and Anti IgG evaluates immune-mediated red blood cell destruction by detecting antibodies or complement proteins. Abnormal findings may suggest autoimmune hemolytic anemia, drug-induced hemolysis, or transfusion reaction. Reflex testing helps distinguish complement activation from IgG involvement, offering insight into immune regulation and hematologic health.
The Haptoglobin Test measures levels of haptoglobin, a protein produced by the liver that binds free hemoglobin released from red blood cells. Low levels may indicate hemolytic anemia, liver disease, or red blood cell destruction, while elevated levels may occur with inflammation or tissue damage. Doctors use this blood test to help diagnose anemia causes, assess liver function, and monitor conditions affecting red blood cell health.
The Red Blood Cell Count Test measures the number of red blood cells circulating in the blood, essential for evaluating oxygen transport and overall health. Abnormal levels may indicate anemia, iron deficiency, vitamin B12 or folate deficiency, dehydration, or bone marrow disorders. This test provides critical insight into hematologic health and is often part of a complete blood count to guide further evaluation.
The Vitamin B12 and Folate Panel Test measures blood levels of vitamin B12 and folate to evaluate nutritional status, red blood cell production, and nervous system health. Deficiencies may cause anemia, fatigue, weakness, neuropathy, or cognitive decline, while elevated levels can indicate liver or kidney disease. Doctors use this panel to diagnose deficiency, monitor therapy, and assess absorption disorders such as pernicious anemia, Crohn’s disease, or celiac disease.
The Glucose-6-Phosphate Dehydrogenase (G6PD) Test measures enzyme activity to detect G6PD deficiency, a genetic condition that can lead to hemolytic anemia when exposed to certain foods, infections, or medications. Doctors order this test to assess unexplained anemia, jaundice, or family history of G6PD deficiency. Results help identify individuals at risk for red blood cell breakdown, guiding treatment, prevention, and safe medication use.
